To Roast the Peppers:Cut the insides out of the peppers so that you have large flat pieces of peppers. Lay the peppers skin side up on a pan and lightly oil them. Roast the peppers in the oven at 350 degrees for about 25 minutes. Place peppers in a zipper top bag and allow to sit for several minutes. (The steam will help seperate the skins from the peppers).
